Description
Technical field
This utility model relates to a kind of cooling piece, a kind of car refrigerators based on double semiconductor chilling plates, belongs to refrigerator art.
Background technology
Quasiconductor refers to electric conductivity material between conductor and insulator under room temperature.Radio, television set and thermometric have a wide range of applications.Quasiconductor refers to that a kind of electric conductivity can be controlled, and scope can material between insulator to conductor.No matter from the perspective of science and technology or economic development, the importance of quasiconductor is all the hugest.Today, most electronic product, all had extremely close connection such as the core cell in the middle of computer, mobile phone or digital audio tape with quasiconductor.Common semi-conducting material has silicon, germanium, GaAs etc., and in the most various semi-conducting material of silicon, the most influential one in business application.
Impurity in quasiconductor is the biggest on the impact of resistivity.When mixing trace impurity in quasiconductor, the cycle potential field near foreign atom is interfered and forms additional bound state, producing the impurity energy level added in forbidden band.Impurity energy level is positioned at above forbidden band near at the bottom of the conduction band.Electronics in impurity energy level is the most easy excitated becomes electronic carrier to conduction band.Quasiconductor can produce electron-hole pair at any temperature, therefore can there is a small amount of conduction hole in N-type semiconductor, can there is a small amount of conduction electrons in P-type semiconductor, and they are referred to as minority carrier.In the various effects of semiconductor device, minority carrier is often played an important role.The electric conductivity of intrinsic semiconductor is relevant with temperature.
Existing it is applied in each electric appliances, structure designs usually not attemperating unit or simple open loop attemperating unit, through actually used discovery, such design is complicated due to the working environment of on-line instrument, the dark noise of photoelectricity testing part is bigger and unstable, it is unfavorable for the stable operation of instrument, and because lacking temperature sensor and carrying out temperature and monitor in real time, temperature cannot be made to control a relatively steady state, during in would generally making car refrigerator, each components and parts are in a temperature environment the lowest, the most each components and parts window easily hazes, affect Instrumental results.If using single semiconductor chilling plate to carry out temperature control, under different ambient temperatures, particularly high temperature, it is impossible to ensure enough temperature control efficiency and temperature accurately cannot be controlled.
Cold-producing medium used by traditional compression-type refrigerating system can cause destruction and the greenhouse gases effect of atmospheric ozone layer, so at refrigerator industry, semiconductor refrigeration system is more and more paid attention to.But it is to use medium heat-transfer that the existing semiconductor cooling device for refrigerator there is also subject matter, the efficiency of heat transfer depends on heat transfer area and material thermal conductivity, the area of semiconductor chilling plate is the least, so causing the unit are heat transfer density of heating surface material and temperature the highest, it is unable to reach the operating mode of semiconductor chilling plate requirement, the efficiency degradation of semiconductor refrigerating.Although the material using high thermal conductivity coefficient can improve heat-transfer effect, but owing to the heat transfer area of heating surface is the least, and the thermal resistance between radiating surface is the biggest, even if so increasing the area of radiating surface, preferable radiating effect can not be reached, and cost will be greatly increased, so the refrigeration structure of quasiconductor is not meet market demands completely at present.
